I honestly don't know what that would be like, as I have been happy with the flavor.. it is actually probably the biggest thing that helped me quit smoking; smoking something with great flavor (One I personally like) instead of cigarette crappy ash tray flavor!
It's also what makes it difficult to smoke a cigarette now.. the flavor. I almost puke now from a cigarette because it tastes so bad in comparison to the e liquids.
The only problem I have found with what I am smoking is that it's harsh on my throat, and when I get sick (as I recently have) I very nearly cannot smoke the e-cig because it hurts my throat (which was sore from coughing from being sick)
